Gelik Thwaxby, a gnemlin within Maldura's Alcove of Reason, knows a great deal of mechanamagica. He has recruited me to recharge the arcane defense pillars within Stoneheart Yards. They helped defend the city from the Aberrants' arcane attacks.

Recharge 5 an arcane defense pillars in the Stoneheart Yards in Thalumbra. These are "obelisk-shaped armatures of gnomish design, as tall as a Teir'Dal, complete with spinning gears and a glowing umbrite focus gem". Possible locations:

( 566, 81, -54 ) /waypoint 566, 81, -54

( 646, 81, 30 ) /waypoint 646, 81, 30

( 539, 67, -133 ) /waypoint 539, 67, -133

Click each pillar.

Kill spawning mobs at each pillar. Mobs have a high damage trauma AoE DoT.
